Evening job on 401

After the washout plugs started leaking on 401s backhead after its steam test yesterday, volunteers went in tonight, dropped the water, removed the plug and ran a tap through the plugholes to thoroughly clean up the threads, as well as clean the plugs again, re-apply graphite paste and re-fit the plugs. The boiler will be re-filled in the morning and the fire lit for another test
